BACKGROUND 1. Technical Field

The present invention relates to a substrate for a display apparatus anda display apparatus.

2. Description of the Related Art

Display apparatuses that achieve higher pixel density (higherdefinition) have been demanded. Higher pixel density decreases a pixelpitch, which often causes color mixture. Increasing the width of a lightshielding layer (black matrix) prevents color mixture, but reduces anaperture ratio, thereby deteriorating luminance.

Arranging the light shielding layer closer to the liquid crystal layerthan the color filter reduces a distance between the light shieldinglayer and the liquid crystal layer. With this configuration, a componentincluded in the light shielding layer may contaminate the liquid crystallayer.

For the foregoing reasons, there is a need for a substrate for a displayapparatus and a display apparatus that can prevent color mixture anddeterioration in luminance, and can prevent liquid crystals from beingcontaminated.

The signal lines SGL are arranged on a planeparallel with the first substrate 21. The signal lines SGL are coupledto the source driver 13. The signal lines SGL are, for example,orthogonal to the scanning lines GCL. In the following description, usedis an XYZ orthogonal coordinate system including the X-axis parallelwith the scanning lines GCL, the Y-axis parallel with the signal linesSGL, and the Z-axis orthogonal to the X-axis and the Y-axis.

As illustrated in FIG. 2, the display apparatus 1 includes a displayregion A1 and a frame region A2. The display region A1 is a region inwhich light is transmitted through the translucent coloring layer 32,and has a rectangular shape, for example. The display region A1 is alsoa region in which an image is displayed by pixels Pix. The frame regionA2 is a belt-shaped region surrounding the display region A1.

A plurality of pixels Pix are arranged in a matrix in the display regionA1 illustrated in FIG. 2. Each pixel Pix includes a plurality ofsub-pixels SPix. The number of the sub-pixels SPix included in the pixelPix is, for example, three. The sub-pixel SPix includes a switchingelement Tr, a liquid crystal capacitor 76, and a holding capacitor 77.The switching element Tr is, for example, a thin film transistor (TFT).The source of the switching element Tr is coupled to the signal lineSGL. The gate of the switching element Tr is coupled to the scanningline GCL. The drain of the switching element Tr is coupled to one end ofthe liquid crystal capacitor 76 and one end of the holding capacitor 77.

One end of theliquid crystal capacitor 76 is coupled to the drain of the switchingelement Tr, and a common potential Vcom is supplied to the other end ofthe liquid crystal capacitor 76. One end of the holding capacitor 77 iscoupled to the drain of the switching element Tr, and the commonpotential Vcom is supplied to the other end of the holding capacitor 77.The holding capacitor 77 is a capacity component for holding a voltagefor image display applied between the counter electrode 61 and the pixelelectrode 62.

The source driver 13 supplies the pixelsignal Vpix to the sub-pixels SPix included in the selected onehorizontal line via the signal line SGL. Display is performed in thesub-pixels Spix for each horizontal line in accordance with the suppliedpixel signal Vpix.

FIG. 4 is a cross-sectional view illustrating a cross-section at adifferent position from that of the cross-section of FIG. 2. Morespecifically, FIG. 4 illustrates a cross section obtained by cutting thedisplay apparatus 1 on a plane including one side of the rectangularpixel Pix. In other words, FIG. 4 illustrates a cross section obtainedby cutting the display apparatus 1 on a plane parallel with the crosssection at a position where the spacer 53 is not included. FIG. 5 is aplan view illustrating the display region of the display apparatusaccording to the embodiment in an enlarged manner. FIG. 6 is a plan viewillustrating an alignment mark formed at the time of manufacturing thedisplay apparatus according to the embodiment.

The first substrate 21 is a substrate made of glass, for example. Thetranslucent coloring layer 32 is a coloring layer including a pluralityof color regions (a color region 32R, a color region 32G, and a colorregion 32B). The translucent coloring layer 32 overlaps with one surfaceof the first substrate 21. The color region 32R is a red region, thecolor region 32G is a green region, and the color region 32B is a blueregion. As illustrated in FIG. 5, the color regions are arranged in amatrix. For example, the color region 32R, the color region 32G, and thecolor region 32B are sequentially arranged in the X-direction, and thesame color regions are arranged in the Y-direction. That is, a column ofcolor regions 32R arranged in the Y-direction, a column of color regions32G arranged in the Y-direction, and a column of color regions 32Barranged in the Y-direction are sequentially arranged in theX-direction. In the following description, a direction in which thetranslucent coloring layer 32 is provided when viewed from the firstsubstrate 21 is represented as +Z-direction.

As illustrated in FIG. 3, the translucent coloring layer 32 is formed onthe first substrate 21 in a part of the frame region A2. The translucentcoloring layer 32 arranged in the frame region A2 is positioned so as tooverlap with the spacer 53 arranged in the frame region A2, and supportsthe spacer 53. On the other hand, as illustrated in FIG. 4, thetranslucent coloring layer 32 is not arranged in a part of the frameregion A2 not overlapping with the spacer 53.

The translucent coloring layer 32 is manufactured using aphotolithography method, for example. First, for example, a blue colorresist is applied to the first substrate 21, and the first substrate 21is caused to spin. After the color resist is dried under reducedpressure, the color resist is irradiated with ultraviolet rays via amask. Thereafter, the color resist is rinsed to remove an excessportion, and the color resist remaining on the first substrate 21 iscured by baking. The process described above from the application of thecolor resist to the baking of the color resist is repeated using a redcolor resist and a green color resist. This process allows thetranslucent coloring layer 32 including the color region 32R, the colorregion 32G, and the color region 32B to be formed on the first substrate21.

Alignment marks 211 on the first substrate 21 illustrated in FIG. 6 areformed with a blue color resist. That is, the alignment marks 211 areformed in a process of forming the color region 32B on the firstsubstrate 21. The alignment mark 211 is a mark used for positioning thedisplay apparatus 1 in a manufacturing process of the display apparatus1. This eliminates one of the manufacturing processes of the displayapparatus 1 in comparison with formation of the alignment mark with ablack color resist (black matrix) as in the related art, and thusimproves manufacturing efficiency of the display apparatus 1.

The first translucent resin layer 41 is a transparent layer made of aresin, more specifically, an insulating resin. That is, the firsttranslucent resin layer 41 is a transparent insulating member. The firsttranslucent resin layer 41 overlaps with the translucent coloring layer32 in the +Z-direction. The area of the first translucent resin layer 41is identical to the area of the first substrate 21 when viewed in theZ-direction, for example. As illustrated in FIGS. 3 and 4, the firsttranslucent resin layer 41 is in contact with the first substrate 21 inat least part of the frame region A2. The first translucent resin layer41 is made of, for example, a photo-curable resin, which is applied tothe translucent coloring layer 32 and irradiated with ultraviolet raysto be cured.

The light shielding layer 33 is what is called a black matrix. The lightshielding layer 33 overlaps with the first translucent resin layer 41 inthe +Z-direction. Forming the light shielding layer 33 on the surface ofthe translucent coloring layer 32 may often cause variations in shape ofthe light shielding layer 33 depending on dimensional accuracy of thetranslucent coloring layer 32. In contrast, forming the light shieldinglayer 33 on a flat surface of the first translucent resin layer 41prevents variations in shape of the light shielding layer 33. Asillustrated in FIG. 5, the light shielding layer 33 is arranged in agrid-like manner. Specifically, the light shielding layer 33 overlapswith boundaries between adjacent color regions (a boundary between thecolor region 32R and the color region 32G adjacent to each other, aboundary between the color region 32G and the color region 32B adjacentto each other, a boundary between the color region 32B and the colorregion 32R adjacent to each other, a boundary between adjacent two colorregions 32R, a boundary between adjacent two color regions 32G, and aboundary between adjacent two color regions 32B). The light shieldinglayer 33 is a single layer, for example. That is, one light shieldinglayer 33 overlaps with the first substrate 21 both in the display regionA1 and the frame region A2, when viewed in the Z-direction.

A second translucent resin layer 42 is a transparent layer made of aresin, more specifically an insulating resin. That is, the secondtranslucent resin layer 42 is a transparent insulating member. Thesecond translucent resin layer 42 overlaps with the light shieldinglayer 33 in the +Z-direction. For example, the area of the secondtranslucent resin layer 42 is identical to the area of the firstsubstrate 21 when viewed in the Z-direction. The second translucentresin layer 42 is, for example, a photo-curable resin, which is appliedto the first translucent resin layer 41 and the light shielding layer 33and irradiated with ultraviolet rays to be cured.

The spacer 53 is a member for maintaining the thickness (cell gap) ofthe liquid crystal layer 5. The spacer 53 overlaps with the secondtranslucent resin layer 42 in the +Z-direction. The spacer 53 alsooverlaps with the light shielding layer 33. The spacer 53 is preferablyarranged at a crossing portion of the grid-like light shielding layer33. As illustrated in FIG. 3, the width of the spacer 53 in theX-direction is smaller than the width of the light shielding layer 33.Similarly, the width of the spacer 53 in the Y-direction is smaller thanthe width of the light shielding layer 33 in the Y-direction.

The orientation film 51 is a film for orienting liquid crystal moleculesof the liquid crystal layer 5 in a predetermined direction. Theorientation film 51 overlaps with the second translucent resin layer 42in the +Z-direction.

The second substrate 22 is a substrate made of glass, for example, andis parallel with the first substrate 21. The counter electrode 61, aninsulating film 63, and a plurality of pixel electrodes 62 are formed onthe second substrate 22. The counter electrode 61 is, for example, atransparent electrode. Specifically, the counter electrode 61 is, forexample, indium tin oxide (ITO). The counter electrode 61 overlaps withthe second substrate 22 in the −Z-direction. For example, the counterelectrode 61 is formed on the surface of the second substrate 22 using asputtering method. The insulating film 63 overlaps with the counterelectrode 61 in the −Z-direction. The pixel electrode 62 is, forexample, ITO. The pixel electrode 62 is formed on the surface of theinsulating film 63 using the sputtering method, for example. The pixelelectrode 62 is insulated from the counter electrode 61 by theinsulating film 63. The pixel electrodes 62 are arranged in a matrix.One pixel electrode 62 corresponds to one sub-pixel SPix. One pixelelectrode 62 includes a plurality of slits 621. An electric fieldgenerated between the counter electrode 61 and the pixel electrode 62acts on the liquid crystal layer 5 via the slit 621. An orientation film52 is arranged on the pixel electrode 62 in the −Z-direction. Forexample, a backlight is arranged on the second substrate 22 in the+Z-direction. Light from the backlight sequentially passes through thesecond substrate 22, the liquid crystal layer 5, and the substrate 10for a display apparatus, and is emitted toward the first substrate 21 inthe −Z-direction.

The liquid crystal layer 5 can change light transmittance in accordancewith the state of an electric field. The display apparatus 1 is adisplay apparatus of a fringe field switching (FFS) system, for example.The electric field of the liquid crystal layer 5 is changed by thecounter electrode 61 and the pixel electrode 62.

The display apparatus 1 is not necessarily the display apparatus of theFFS system. For example, the display apparatus 1 may be a displayapparatus of a twisted nematic (TN) system, a vertical alignment (VA)system, or an in plane switching (IPS) system. The display apparatus 1may also be a reflective liquid crystal display apparatus. When thedisplay apparatus 1 is a reflective liquid crystal display apparatus,the display apparatus 1 has a reflective electrode that reflects lightas the pixel electrode 62 instead of the transparent electrode, or has areflective plate and the like on the second substrate 22 in the+Z-direction.

The number of colors of the color regions included in the translucentcoloring layer 32 is not limited to three, and may be any number as longas it is plural. For example, the translucent coloring layer 32 mayinclude a white color region in addition to the color region 32R, thecolor region 32G, and the color region 32B.

The first translucent resin layer 41 and the second translucent resinlayer 42 may not be completely transparent as long as they havetranslucency. It is preferable that change in color of light transmittedthrough the translucent coloring layer 32 which is caused by the firsttranslucent resin layer 41 and the second translucent resin layer 42 isas little as possible. Thus, the first translucent resin layer 41 andthe second translucent resin layer 42 are preferably close totransparent as much as possible.

As described above, the substrate 10 for a display apparatus includes:the first substrate 21; the translucent coloring layer 32 that overlapswith the first substrate 21; the first translucent resin layer 41 thatoverlaps with the translucent coloring layer 32 on the opposite side (inthe +Z-direction) to the first substrate 21 side; the light shieldinglayer 33 that overlaps with the first translucent resin layer 41 on theopposite side (in the +Z-direction) to the first substrate 21 side; andthe second translucent resin layer 42 that overlaps with the lightshielding layer 33 on the opposite side (in the +Z-direction) to thefirst substrate 21 side. Arranging the light shielding layer 33 closerto the liquid crystal layer 5 than the translucent coloring layer 32prevents color mixture. The color mixture is a phenomenon in which lighttransmitted through adjacent color regions having different colorsenters the eyes of a person when the person views the display region A1in an oblique direction (a direction forming an angle to the Z-axis).

The above configuration widens the path of the light (optical path) thatpasses through the translucent coloring layer 32 in an oblique direction(direction forming an angle to the Z-axis), thereby improving luminancewhen the display apparatus 1 is viewed in the oblique direction.Arranging the second translucent resin layer 42 between the lightshielding layer 33 and the liquid crystal layer 5 prevents the liquidcrystal layer 5 from being contaminated by the light shielding layer 33.The substrate 10 for a display apparatus and the display apparatus 1thus can prevent color mixture and deterioration in luminance, as wellas being capable of preventing contamination of liquid crystals. Theorientation film 51 is very thin in comparison to the light shieldinglayer 33, and thus only with the orientation film 51, it is difficult toprevent contamination of the liquid crystal layer 5 by the lightshielding layer 33.

In the substrate 10 for a display apparatus, the light shielding layer33 is formed on the surface of the first translucent resin layer 41instead of the surface of the translucent coloring layer 32. Thisprevents variations in shape of the light shielding layer 33, therebyallowing the light shielding layer 33 to be easily narrowed. Theaperture ratio of the substrate 10 for a display apparatus thusimproves, thereby improving transmittance (a ratio of emitted lightquantity to incident light quantity) in the display apparatus 1.

First Modification

FIG. 7 is a cross-sectional view of a display apparatus according to afirst modification of the embodiment. More specifically, FIG. 7illustrates a cross section obtained by cutting a display apparatus 1Aaccording to the first modification on a plane including middle pointsof two parallel sides of the rectangular pixel Pix. A substrate 10A fora display device according to the first modification includes a secondtranslucent resin layer 42A different from the second translucent resinlayer 42 described above, and a spacer 421 different from the spacer 53described above.

The second translucent resin layer 42A is a transparent layer made of aresin. The second translucent resin layer 42A overlaps with the lightshielding layer 33 in the +Z-direction. For example, the area of thesecond translucent resin layer 42A is identical to the area of the firstsubstrate 21 when viewed in the Z-direction. The second translucentresin layer 42A is, for example, a photo-curable resin, which is appliedto the first translucent resin layer 41 and the light shielding layer 33and irradiated with ultraviolet rays to be cured.

The spacer 421 is a member for maintaining the thickness (cell gap) ofthe liquid crystal layer 5. As illustrated in FIG. 7, the spacer 421 ismade of the same material of that of the second translucent resin layer42A, and is formed integrally with the second translucent resin layer42A. For example, the spacer 421 is formed by half exposure. That is, aportion of the second translucent resin layer 42A excluding the spacer421 is irradiated with a reduced amount of ultraviolet rays. Removing anon-cured portion from the second translucent resin layer 42A forms thespacer 421. Manufacturing the spacer 421 and the second translucentresin layer 42A in the same process improves manufacturing efficiency.

Second Modification

FIG. 8 is a cross-sectional view of the display device according to asecond modification of the embodiment. More specifically, FIG. 8illustrates a cross section obtained by cutting a display device 1Baccording to the second modification on a plane including middle pointsof two parallel sides of the rectangular pixel Pix. The substrate 10Bfor a display device according to the second modification includes asecond translucent resin layer 42B different from the second translucentresin layer 42 described above.

The second translucent resin layer 42B is a transparent layer made of aresin. The second translucent resin layer 42B overlaps with the lightshielding layer 33 in the +Z-direction. The area of the secondtranslucent resin layer 42B is different from the area of the firstsubstrate 21 when viewed in the Z-direction. That is, the secondtranslucent resin layer 42B overlaps with the light shielding layer 33,while not overlapping with a part of the first translucent resin layer41, as illustrated in FIG. 8. This configuration reduces an amount ofthe resin to be used in comparison to the embodiment described above.The second translucent resin layer 42B is made of, for example, aphoto-curable resin, which is applied to the light shielding layer 33and irradiated with ultraviolet rays to be cured.

Specifically, the second translucent resin layer 42B is arranged in agrid-like manner similarly to the light shielding layer 33. The secondtranslucent resin layer 42B is arranged only at a position where thelight shielding layer 33 is arranged, and covers a part of the surfaceof the light shielding layer 33 that is not in contact with the firsttranslucent resin layer 41. The second modification is the same as thefirst modification in that the light shielding layer 33 is interposedbetween the first translucent resin layer 41 and the second translucentresin layer 42B to be protected, and is different from the firstmodification in that the second translucent resin layer 42B is notarranged on the entire surface of the first substrate 21. As illustratedin FIG. 8, the width of the second translucent resin layer 42B in theX-direction is larger than the width of the light shielding layer 33.The same applies to widths in the Y-direction. This configuration allowsthe second translucent resin layer 42B to cover the light shieldinglayer 33, thereby preventing the liquid crystal layer 5 from beingcontaminated by the light shielding layer 33. The spacer 53 is arrangedat a position to overlap with the light shielding layer 33 when viewedin the Z-direction. The second translucent resin layer 42B and thespacer 53 may be made of the same resin material. In this case, thespacer 53 is formed after the second translucent resin layer 42B isformed.

As illustrated in FIG. 8, a gap between adjacent light shielding layers33 is not filled with the second translucent resin layer 42B on a crosssection vertical to the first substrate 21. Accordingly, the orientationfilm 51 and the liquid crystal layer 5 are partially arranged betweenadjacent light shielding layers 33.

Third Modification

FIG. 9 is a cross-sectional view of the display device according to athird modification of the embodiment. More specifically, FIG. 9illustrates a cross section obtained by cutting a display device 1Caccording to the third modification on a plane including middle pointsof two parallel sides of the rectangular pixel Pix. A substrate 10C fora display device according to the third modification includes a secondtranslucent resin layer 42C different from the second translucent resinlayer 42 described above, and a spacer 421C different from the spacer 53described above.

The second translucent resin layer 42C is a transparent layer made of aresin. The second translucent resin layer 42C overlaps with the lightshielding layer 33 in the +Z-direction. The area of the secondtranslucent resin layer 42C is smaller than the area of the firstsubstrate 21 when viewed in the Z-direction. That is, the secondtranslucent resin layer 42C overlaps with the light shielding layer 33,while not overlapping with a part of the first translucent resin layer41, as illustrated in FIG. 9. This configuration reduces an amount ofthe resin to be used in comparison to the embodiment described above.The second translucent resin layer 42C is, for example, a photo-curableresin, which is applied to the light shielding layer 33 and irradiatedwith ultraviolet rays to be cured.

Specifically, the second translucent resin layer 42C is arranged in agrid-like manner similarly to the light shielding layer 33. Asillustrated in FIG. 9, the width of the second translucent resin layer42C in the X-direction is larger than the width of the light shieldinglayer 33. The same applies to widths in the Y-direction. Thisconfiguration allows the second translucent resin layer 42C to cover thelight shielding layer 33, thereby preventing the liquid crystal layer 5from being contaminated by the light shielding layer 33.

As illustrated in FIG. 9, a gap between adjacent light shielding layers33 is not filled with the second translucent resin layer 42C on a crosssection vertical to the first substrate 21. Accordingly, the orientationfilm 51 and the liquid crystal layer 5 are partially arranged betweenadjacent light shielding layers 33.

The spacer 421C is a member for maintaining the thickness (cell gap) ofthe liquid crystal layer 5. As illustrated in FIG. 9, the spacer 421C ismade of the same material as that of the second translucent resin layer42C, and is formed integrally with the second translucent resin layer42C. For example, the spacer 421C is formed by half exposure. That is, aportion of the second translucent resin layer 42C excluding the spacer421C is irradiated with a reduced amount of ultraviolet rays. Removing anon-cured portion from the second translucent resin layer 42C forms thespacer 421C. Manufacturing the spacer 421C and the second translucentresin layer 42C in the same process improves manufacturing efficiency.

The present invention can naturally provide other advantageous effectsthat are provided by the aspects described in the embodiment above andare clearly defined by the description in the present specification orappropriately conceivable by those skilled in the art.
